[PATCH v7 3/6] perf annotate: Show raw form for jump instruction with indirect target

For jump instructions that does not include target address as direct
operand, use raw value for that. This is needed for certain powerpc
jump instructions that use target address in a register (such as bctr,
btar, ...).

Before:
     ld     r12,32088(r12)
     mtctr  r12
  v  bctr   ffffffffffffca2c
     std    r2,24(r1)
     addis  r12,r2,-1

After:
     ld     r12,32088(r12)
     mtctr  r12
  v  bctr
     std    r2,24(r1)
     addis  r12,r2,-1
